EPECIFICATION formingpart of Letters Patent No. 719,416, dated February 3, 1903. Application filed June 2, 1902. $erial No. 109,833- (No model.)

To M whont it may concern.-

Be it known that I, JOSHUA XV. ATLEE, a citizen of the United States, and a resident of Riverton, State of New Jersey, have invented certain new and useful Improvements in Ventilating-Ports for Vessels, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to certain new and useful improvements in ports or port-holes for vessels, and has for its object the production of a port-hole having a glass or closure which is easily secured in position and at the same time may be quickly displaced therefrom and held conveniently out of the way when not in use.

A further object of my invention is to provide a casing for said port-hole which will allow of a good ventilation by a supply of fresh air to the interior of the vessel and will at the same time prevent water from entering the interior of the vessel should the waves become high enough to cover the port or should the vessel roll suffieiently to force the same below the surface of the water.

A further object is to provide a casing for said port-hole which when once having been covered or filled with water will quickly be cleared of the same, and the water will be drained away without becoming lodged in any of the recesses of said casing; and a further object is to provide a fastening for said glass or cover whereby the same may be quickly and positively secured in position within the casing and may be quickly and easily raised to a position to be out of the way when not in use.

For a full and detailed description reference may be had to the accompanying drawings, forming a part of this specification, in which- Figure 1 represents a vertical elevation of my improved ventilating-port, the left-hand half being shown in vertical longitudinal section and the front thereof being removed. Fig. 2 shows a vertical transverse section taken substantially upon the line 2 2 of Fig. 1. Fig. 3 shows a plan View of my improved fastening device, the casing being shown in horizontal section; and Fig. 4. is an elevation of the fastening device, the casing also being shown in section.

Similar numerals of reference apply to corresponding parts throughout the figures of the drawings.

lindicates the main casing, having front and back plates 2 and 3, through the lower portion of which suitable openings are provided, one of which, that toward the interior of the vessel, is adapted to be closed by the cover or glass 4:. To the exterior of the plate 2 is fastened a flanged plate 5, the inwardlyprojecting flange 6 of which is adapted to engage the frame or ring 1, carrying the glass 7. This ring 4 is provided at one side with an inwardly projecting flange 8, adjacent to which is a rubber gasket or packing 9. The other side of the ring is provided with screwthreads adapted to hold the retaining-ring 10 in position. Upon the inner side of said ring 1 a bushing or packing 11 is provided, the same being set in a groove in said ring and adapted to contact with the flange 6 of the plate 5.

12 indicates the outer shell of the vessel, which has an opening corresponding to the opening in the outer plate 3. This shell and plate are united by suitable bolts 13, and a ring 14 is inserted in both openings to give the same a finished appearance and to prevent water from entering between the shell and plate. At the top of the casing 1 an auxiliary casing 15 is provided, which contains one or more spring-drums 16. These springdrums carry flexible ribbons 17, which are connected at their, lower ends to the retaining-ring at of the glass or cover. These springdrums counterbalance the weight of the cover or glass, and when slight force is used to raise the cover the same will ascend to the position indicated in dotted lines in Fig. 1. It will be seen that this arrangement operates in a manner similar to that of counterbalanced window-frames or shade-rollers.

Upon one or both sides of the central easing 15 are provided flanged openings 18,which are surmounted by elbow-casings 19, having interiorly-projecting flanges 20,which slightly decrease the outlet of the flanged opening 18 and form valve-seats, hereinafter to be more particularly described.

21 21, 4110., indicate bars which extend transversely of the casing and are attached to the plates 2 and 3. These bars are arranged in a manner shown in Fig. l to form a retaining-receptacle for a float valve or ball 22, which is of'sufficient size to enter the fianged opening 18, but will be stopped by the flange and close said opening, thus forming a check-valve to prevent water from entering the interior of the vessel. It will be seen should the opening in the exterior plate become submerged any tendency of the water to enter therethrough and be forced into the interior of the vessel through the opening 18 and the casing 19 would raise the float or ball 22 and immediately close said opening, while at other times fresh air from the outside is free to'enter. I provide, however, a cap 23, which is adapted to completely close the easing 19 by being screwed over the flanged portion 24.

At the lowest point of the space between the plates 2 and 3 I provide an outlet 25, which serves as a scupper to drain oif any water which may be entrapped between said plates when the port has been submerged. This opening therefore immediately returns the entrapped water to the exterior of the vessel and preserves all the operative parts of the port in a dry and clean condition. This open- 'tate said screw-shaft or bolt.

ing is also provided with a bushing, as indicated at 26, to prevent water from entering between the shell of the vessel and the plate 3.

The fastening devices for the cover or glass 4 are constructed as follows: 27 indicates screw-shafts or bolts, each end of which have bearings inthe casing 2 and 3, respectively, and the inner end is provided with a suitable handle or wrench 28, which is adapted to ro- Said screwshaft also has a flanged portion 29 for retaining the same in position longitudinally. Upon this bolt or screw-shaft is niounteda U-shaped nut 30, which is moved backward and forward thereon as the screw is turned either to the left or right. The glass-retaining ring 4 is provided with cars 31, which project radially and have notches or recesses in their lower sides of such a size as to fit over and rest upon the screw-shafts 27. These ears are of a thickness slightly less than the distance between the arms of the U-shaped nut, so that they can easily enter between the said arms without binding. The upper edges of the arms and the lower edges of the ears are beveled slightly to form guides, so that said ears may easily enter the space between the arms of the nuts. It will now be seen that when the glass or cover is lowered, the nuts being in a central position upon the bolts, the ears will enter the recesses between the arms of said nuts and will rest upon said bolts. If then the handles or wrenches 28 are turned toward the right, said glass or cover will be forced inwardly and the packing l1 engage firmly against the flange 6 of the plate 5. By turning said handles toward the left the nuts are forced outwardly, and thereby the glass or cover is released and is free to ascend vertically into the space between the plates.

I do not wish to be limited to the exact arrangement of parts and details of form herein set forth, and minor changes may be made Without departing vention-as, for instance, more than two clamping-bolts may be used and only one valved inlet maybe provided, if so desired; but

What I do claim as my invention, and desire to protect by Letters Patent, is

1. In aventilating-port for vessels, a casing comprising inner and outer plates having openings to admit light and air, a glass or cover adapted to close one of said openings and be retained in position within said casing at its upper portion when not in use, openings in the upper portion of said casing for the admission of air and an opening at the lowest portion of said casing communicating with the exterior of the vessel and adapted to carry off entrapped water, substantially as described.
